I am running xubuntu 18.04.
I recently installed the nvidia proprietary drivers.
I have three monitors.
When I lock my screen using light-locker my left-most monitor turns off and the other two monitors mirror each other at a 800x600 resolution.
I had a similar-but-not-identical problem with my login screen, which I solved: How to adjust display settings for LightDM greeter on 18.04?
How do I apply a similar solution to my lock screen? I'm assuming it's a different configuration file but I can't find where it might be.
Here is the output of
light-locker --debug, if it is helpful.
